To all whom it may concern I Be it known that I, CHARLES A. LUCK,

a citizen of the United-States, and a resident of Toledo in the county of Lucas and State 5 of Ohio, have invented a certain} new and useful Pen-Point Holder; and I do hereby declare the following. to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which marked thereon, which form apart of this specification.

fountain pens, and has for its object the provlsion of simple and efiicient means for securing the pen point and feed bar to the pen point carrying section of a fountain pen, which means is operable to firmly hold said parts in assembled relation, and also to permit an easy separation or assembling thereof. I With the present constructionof fountainpens considerable pressure is applied to the feed bar and pen point in forcing them in holding position in the pen point carrying section, such pressure usually being applied by a machine, thereby rendering it extremely difficult to remove the pen point and feed bar from the carrying section without injury to person. v An object of this invention is to render such removal ofthe pen point and feed bar easy and without danger of injuring the pen' point. Further objects and advhntages of the invention will be apparent from the following detaileddes'cription thereof.

While the invention in .its broader aspect is capable of embodiment in numerous forms,

-. a preferred embodiment thereof and a few modifications of a part thereof are. illus trated in the. accompanying drawings, in

which,

Figure 1 is aside view, of a fountain pen embodying the invention. Fig. 2'isan enlarged fragmentary view of the pen point carrying sectiom and lock member in central longitudinal section and relatively posi tioned to place the bores thereof in alinement. Fig; 3 is an enlarged view of the pen f'point carrying section and lock member in centra longitudinal section and relatively positioned to throw the bores thereof out of it appertains to make and use the same, ref-v This invention relates more particularly to Specification of Letters Patent.

axial alinement Fig. 4 is an outer end view of the art shown in Fig. 3. Figs. 5 and 6 are di erent views of "a pen point and feed bar in assembled relation and provided with'interengaging parts. Fig. 7 is an enlarged fragmentary view of a pen point carrying section and lock member in central longitudinal section and witha feed bar and pen point-positioned therein, the pen point and lock member being provided with interengaging meansg, Fig.- 8 is alsimilarview with the pen point and carrying section provided with interengaging means, and F g. 9 is a similar view with the pen point longi-. tudinally'slotted at its rear end and engag- .in over a positioning pin on the feed bar.

eferring to the drawings, 1 designates the barrel of a fountain pen, 2 the pen point carrying part or section, which is customarily removably fitted into the open inner end of said barrel and provided longitudi nally therethroug'h with the customary bore or passage-way 3 in communication at'its inner end with the interior of the barrel, if r such barrel serves as the ink reservoir, or with the interior of the customary bag (not shown), which may have its mouth fitted over a re'duced'nipple fat the inner e'nd of the carrying section 2, as well understood in the art. .5 and 6 designate the customary feed bar and pen point, respectively, which,

with the. fountain pens now 1n use, are forcefully inserted into the outer end portion of thebore of the carrying section 2 and. fit tightly therein.

.In carrying out my invention, the outer endof the bore 3 of the carrying section is provided with a cylindrical enlargement 7 into which a lock nipple-or. member 8 is fitted for. transverse rotary movements there in. The outer end of this nipple is preferably enlarged without theend of the carrying section to a size substantially equal to the outer end of said section, and is intended to abut thereagainstfas shown. It is also preferable to knurl or roughen the peripheral surface of the nipple enlar ementto facilitates hand gripping thereo when be ing turned in the carrying section. V A bore 9 is providedlongit udinally through the nipple and issubstantiallv of the same diameter as the bore-3.

In the present instance,.tl1e.bore enlargement 7 in thecarrying section 2 istoncentrio with the axis of said section and the section bore*3 and the nipple bore 9. are slightly offset laterally of the section axis and adaptshown in'Figs. 3 and 4. The carrying sec- .are exaggerated in this respect.

tion and nipple bores are of suitable size-to permit a free or comparatively easy insertion of an assembled feed bar 5 and-pen point 6 therein or a removal of the same therefrom when such bores are axially alined.

It is evident that a turning or angular adjustment of the nipple 8 relative to the carrying section 2 from .alined position shown in Fig. 2, will causea firm gripping of the feed bar-and pen point between portions of the carrying section and nipple at opposite sides of their axes, as-is clearly apparent by reference to Figs. 3 and 4, which In other words, a. turning of the nipple within the carrying section from the alined position shown in Fig. 2 causes a camming action to be exerted on the feed bar-and pen point relative to the carrying section to firmly grip them therein, the gripping force on said parts being increased in proportion to the extent of relative turning of the carrying section and nipple. To facilitate a finding of the alined positions of the carrying section and nipple bores, the adjacent peripheral edges of the section and'nipple are provided with notches, lines or marks 10 and 11, respectively, which longitudinally registerwhen the bores of said parts are in axial alinement.

In Figs. 5 and 6 the feed bar 5 is shown as having a pin 12 projected transversely therethrough with its ends projecting beyond' the sides of the feed bar and pos tioned to enter notches l3 in'the respective side edges of the pen point, thus "facilitating an assembling of the feed bar and pen point and the-retaining of the-same mproper position While being inserted in and gripped by the nipple 8 and pen point carrying section 2. If the ends of the pin 12 project beyond the side edges of the pen/ point, the nipple 8 may be provided in opposite sides of its, borewith longitudinally-extending notches 14" for receivingthe respective pin ends. The interengaging of the pin and nipple in this manner causes a turning of the feed bar,

pen point and nipple together relative to the pen point carrying section 2 so that an undue lateral strain will not be placed on the pen point-to throw it out of proper position on the feed bar when the nipple is angularly adjusted.

In Fig.9, the pin 12 of the feed bar is shown as entering slots of notches 15 provided longitudinally in the rear end of the pen point instead of in the side edges thereof.

In Fig, 7 the pen point is shown as being provided with transversely. alined raised portions 16, which are adapted to spring into an annular recess 17 in the nipple to serve to lock or firmly retain the. pen point in the nipple.

In Fig. 8 the pen point carrying section 2 is provided with an internal annular recess 18 into which a transverse ridge or raised portion 19 on the rear end portion of the .pen point may seat, thus serving to lock the 90f the nipple 8 relative to the carrying section 2, the greater will be the pressure of the pen point against the feed bar, and the feed of ink through the capillary passages of the bar reduced accordingly.

An important feature of the present invention isthat it enables the user of the pen to easily remove and replace a pen point, so that steel or other pen points which corrode more or less quickly, can be used in place of the more expensive gold pen points which are now commonly used in fountain pens.

I wish it-understood that my invention is not limited to any specific construction, ar-

rangement or form of the parts, as it is capable of numerous modifications and changes to accomplish the same result without departing from the spirit of the claims. I also wish it understood that while I have particularly described my invention in connection with a fountain pen, it may be effectively used,- in connection with pen holders other than of the fountain type.
